SIMbN YASULAITIS, OF BROOKLYN, NEW YORK.

LIFE-BOAT.

To all whom z't may concern Be it known that I, SIMON YAsULAnis, a citizen of Russia, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful 1m provenients .in Life-Boats; and I doliereby declare the following" to be a full, clear. and

exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lH'lPIOVQIIIGIIiS in life boats.

One object of the present invention is to provide a. life boat of novel construction which is strong and durable and which will stand rough usage in the sea.

Another object is to provide an improved construction of lifeboat which will be perfectly sea worthy andv which will not be liable to leak. I v

A further object is to provide an improved life boat which will be practically puncture-proof and which will be practically indestructible.

A further object is to provide a life boat havin'g'a novel and efiicient and improved means for launching the same-from a ship, whereby the loosening, by hand, of davit ropes, or other lines, is obviated, the release of the boat being automatic as soon as it touches the water and floats.

Dther objects and advantages will be apparent'from the following description when taken in connection with the accompanying drawing. I

Application filed October 31, 1917. Serial No. 199,472.

Referring particularly to the acconipany ing drawings, there is shown a life boat made in accordance with my invention.

The walls of the boat are formed from a til? plurality of layers of different materials,

which will now be described and particularly referred to by reference numerals.

The innermost layer 1.0 is formed troina waterproof fabric. Next, outwz'irdly of this layer 10 is a layer of closely woven wire screen 11, and outwardly of this screen is a second layer of screen cloth 12. Between these layers of screen there 13 disposed the spring steel bracing members. shown in detail in Fig. t. These bracing members each include longitudinal strips of spring steel 13 which extend from one end of the boat to the other, and at thesides thereof. Dis posed transversely of the steel strips 13, and secured thereto attheir intern'ieciate portions, 'are the shorter strips of steel 1%. Also secured to the strips 13 andv 1t, and extending longitudinally thereof, are the shorter strips 15, further strips 16 being secured to the strips 1i and 15. (lross strips 16 are secured at the points wnere the strips 15 are joined to the strips Outwardly of the screen 12 there is disposed a layer of waterproof cloth .17, such as rubberized .fabric. Next outwardly ot the layer 17 are two layers of canvas 18 and l9, and next outwardly of these layers is a layer of rubber and fabric 20, similar int-on struction to the outer shoe of an automobile tire.

Outwardly of the layer 20 is a l: of canvas 21. Outwardly oi the is a' layer of closely woven wire 22 and outwardly of this screen, til ing the outermost layer or surface i body of the boat, is adayer of heavy wi rope or cable woven into the form til. a net,

as shown at 23.

submerged objects.

The keel 24 consists of a length of heavy wire cable or rope, while slightly smaller wire ropes or cables 25 form the gunwales o t-the boat/ ice til 53' a trance of water.

Thus there provided a simple and practically in lestr1ictihle boat, and one which is comparatively light in weight. A

To the gunwales oi? the boat are secured the longitudinally extending metal strips 2-6, and connected to these strips are the sheets of waterproof fabric 27. A pair of longitiulinally extending and outwardly bowed metal strips :28 are pivotally connected to- ;gether at their ends and to the connected ends or the strips 26, as shown at 29. These strips 28 are adapted to be swung into position on the gunwales oi. the boat at times, and into overlapping relations above the boat at times. Tl he remaining marginal edges of the sheets 27 are secured to these bowed strips and together with said strips, .i'orm a cover or roof, which, when raised, as shown in l. and 5, will protect the occupants of the boat in inclement weather.

in each of the fabric sheets a resecured the porthole frames 30 and the Vertical.ventilating; tubes 31, said tubes having the caps or hoods on their upper ends to prevent the enr-i door 252 is hinged to each of the frames 30 to close the opening therethrough, and is formed with a bifurcated extension 33 for the reception of the turn-hiitton 3% carried by the adjacent side of the frame.

liixtending rearwardly from the stern of the boat, at the level of the gunwales, is a frame 35 to the outer end of'which is connected the upturned end portion of an L- shaped member which is secured to the keel, as shown at 3-6, Within this frame, and secured. to the stern of the boat, is a vertical frame 3i" n which is mounted a vertical shaft 3e carryiiur a rudder blade on the lower end, as 3%), the lower end of said shaft being journaled in the horizontal portion of the L-shaped member 36. llilounted in the upper and lower portions oi the Vertical frame are the shafts 40 a nil-ll, the upper one having a sprocl'aet wheel 1-2, while the lower one carrir-s sprocket wheel l3 and a propeller t-il. A drive chain iii is engaged around these sprocket. wheels, as clearly shown. Secured to the inner eirid of the rear oil the boat is a transwrsely disposed and vertically arranged plate t6 and through this plate ex- 40, said inner end of the shaft being provided with a crank handle d7 for rotating the shaft 4:0 with the transmission of power to the propeller to drive the boat. l ornied on the plate i6 is a horizontal porthe inneinend portion of the upper tion 48 and rotatably mounted on this portion is a wheel .49 which is connected to the rudder shaft by means of the cords 50.

Mounted on the how of the boat, as well as on the stern thereof, is an outwardly extending bracket Pivotally mounted on each of these bra kets is a vertically disposed hook member 52, said member being 11or mally urged toward the boat by a spring The hook member is arranged to be moved outwardly and engaged with a ring 54 carried by the lower end of one of the. davit ropes When the boat is lowered to the water, and floats, the said ropes'and rings will naturally sag downwardly and out of engagement with the hooks, thereby permitting the springs to draw the hooks in 1 wardly toward the boat and completely out of the way. When the hooks are engaged with the rings of the davit ropes the weight of the boat will hold them in such position against the springs 53. Thus the usual method of casting oil lines when a boat is launched from a ship, or detaching hooks or ropes from the davits, is entirely obviated.

From the foregoing it will be seen that I have provided a novel and simple as Well as durable life boat, and one which is easily and quickly launched from a ship, even in a rough sea. Furthermore, it will be seen that the boat is capable of properly protecting the occupants from the weather, while at the same time means are provided whereby the occupants can propel the boat and steer the same, as desired.

Furthermore, the construction of the hull of the boatis such that danger of'leakage or crushing thereof is unlikely, as the sides of the hull are possessed of such elasticity that bending or denting is as far as-the damage will go.

What is claimed is:

A boat construction consisting of layers of waterproof fabric, layers of woven wire screen. stiffening means, layers of waxed and oiled fabric, spring metal bracing members disposed between certain of the layers, and

.an outer shell of'woven metal nettin the b7 keel and gunwales of the boat being formed from lengths of metal cable.

In testimony whereofil aiiix my signature in the presence of two itnesses.
